Of course panic sell it is psychological effect, but always is starting from mathemathic/statistic calculations or some extremely bad news for the project.
In my opinion the real price of Bitcoin is much lower than what we see on the market today, and the panic sell for Bitcoin is very real.
Psychological effect. with so many issues and drastic price drop. Many people take this action, and this is real.
Although from what I see, this is part of the market action to correction the price and restock the supply.
When you have no enough information about bitcoin you can easily panic and you will sell with a loss.
I would say it's not good because we are here to make money that is why we invested, we need to improve our knowledge as that is the only way to succeed here. Panic selling will create opportunity for smart people because they'll buy cheap.
Its a very god question because its not an easy game you must have to understand this business because to buy bitcoin or to sell bitcoin it need full concentration first of all you need to know about its price if you come to know that the price is low then buy bitcoin as much as you can and then keep it on hold because that wait can change your life so no need to make any panic just wait for a right time and when you know that the price is high then sell it.
